The N95 respirator mask is primarily used for which precautions?

• A. Eye protection
• B. Routine surgical procedures
• C. Airborne precautions to protect against airborne pathogens
• D. Contact precautions

Answer: (C)

The main idea is protection through inhalation filtration. An N95 respirator is designed to filter at least 95% of airborne particles and seal tightly to the face, so it reduces the wearer’s inhalation of airborne pathogens. This makes it the go-to protection for airborne precautions, such as diseases spread by aerosols, and for procedures that generate aerosols.

Eye protection is important in many settings, but the respirator’s primary purpose is to protect the lungs and airways from inhaled particles, not to shield the eyes. Routine surgical procedures often use a surgical mask to guard against splashes and larger droplets rather than filter the air for fine aerosols. Contact precautions focus on preventing transfer via surfaces and direct contact, typically requiring gloves and gowns rather than relying on a respirator for protection.
